CLOTH-ROLLING MACHIN E.

" Application ma February s, 1927. serial No. 166,775.

This invention relates to machines for winding the cloth Ainto rolls, which rolls are subsequently sliced transversely to produce 4a number of narrow rolls of cloth tape, and

for the reason that when the roll is sliced transversely the stri s thus formed, if the cloth is wrinkled, w11 not present uniform widths. f-

It is therefore an object of the present invention to provide a rolling machine which rolls the cloth smoothly and positivel precludes the formation of wrinkles in tlie cloth when rolled. y

In the machines of this character which are now in general use and on the market, the cloth is rolled on a positively driven hatching spindle and it ,iS obvious that as the diameter of the roll increases, the speed at which the cloth feeds to the roll increases to such an extent that even the highly skilled operators have dilliculty in maintaining the edges of the outermost convolutions .in substantial alinement.y This results in considerable waste of` material due to the fact that the roll of cloth must havevthe ends where the edges of the convolutions are. uneven, trimmed offbefore the remainl der can be sliced. There is also ever present thev ossibility of wrinkling of the cloth where t e. feed of the same becomes excessive,

It is therefore a further object of the .present invention to rovide an improved rolling machine of this character in which the-cloth is fed ata uniform rate of speed irrespectiveof the size of the roll being formed. v

The invention furthermore comprehends a cloth rolling machine which specifically includes a loosely mounted batchingspindle upon which the cloth is rolled, with means v engaging and exerting a frictional drivin pressure upon the periphery of the clot roll at substantially diametricall opposite points, which means causes the c oth to kbe rolled by frictional driving pressure upon the periphery of the cloth ,roll, thereb causing the cloth to be fed upon the rol at a uniform rate of s eed, which speed admits of the operation o the machine without constant attention so that a single operator may care for a plurality of machines.

The invention more s ecifically comprehends a loosely mounte hatching spindle upon which the cloth is rolled, together with a pair. of positively driven drums or rollers engaging and exertin a pressure uponthe cloth roll at diametrlcally opposite points of the periphery thereof and in'which thev cloth is trained around one of said drums or rollers so that the accurate measurement of the yardage may be obtained by means of a counter coacting with said drums or rollers. l a

A further object of the invention resides 1n the provision of a rolling machine which includes a loosely mounted hatching spindle upon which the cloth is rolled and a pair of positively drivenV drums or rollers engaging or exerting a pressure upon the cloth roll at diametrically opposite points of the periphery thereof, which drums or rollers exert a vise-like rip upon the cloth roll lonv the hatching spindle to inherentl prevent the formation of wrinkles in the ro l thus formed.

Other objects and advantages reside in the simplicity of construction, the economy with which the machine may be produced and operated, and the general eliiclency derived therefrom.

Withthe above recited and 'other objects in view, reference is had to the following specification and accompanying drawings .1n which therel is exhibited one example or embodiment of the invention which is in no way intended as a limitation upon the scope of the appended claims as it 1s to be 7 clearlyunderstood that variations and lmodifications which properly fall within the scope ofsaid claims may be resorted tov when found expedient. f

In the drawings l Figure 1 is a side view of a machine lconstructed in accordance with theA invention; Fig. 2 is a front viewof the machine.; Fig. 3 is a fragmentaryr enlarged horizontal sectional view through the batching spindle and its bearings taken approximately on the line indicated at'3-3 in Fig. 2;` Fig. 4 is a fragmentaryA enlarged transversesectional view taken approximately on the line 4-4. of Fig. 2. -Referring to the drawings by characters of reference, 10 designates the main frame los of the machine which is provided with bearing brackets 11 carrying bearings 12 and 13 in which alined stub shafts 14 and 15 are mounted. Either one or both of the stub shafts may be axially movable in their bearings, but, as illust-rated, the stub shaft 14 lis rigid or immovable while the stub shaft 15 is axially movable or shiftable through the bearing 13. rlhe stub shafts 14 and 15 carry on their inner ends respectively, journal bearings 16 and 17, having tapered or ared bores 18 for receiving the tapered or frusto-conical opposite extremities 19 of a hatching spindle 20. As illustrated, the spindle is inserted in or removed from the journal bearings by shift-ing or moving the stub shaft 15 axially, and after the spindle is journaled the stub shaft is locked against outward shifting movement by a lock pin 21 inserted through the alined openings in the bearing 13 and stub shaft 15. It is obvious that this may be accomplished in any desired manner so that the hatching spindle may be readily removed from or mounted in the journal bearings. The hatching spindle is adapted to receive thereon the usual tubular core C upon which the cloth or material M to be rolled is adapted to be wound. The main frame 10 has mounted transversely therein for turning movement, a pair of superposed shafts 22 and 23, each of which has keyed thereto at one end, a pair of sprockets 24 and 25, and 26 and 27. A driving sprocket chain 28 is trained around a driving sprocket 29 keyed or secured to a shaft 30 of a driving pulley 31 and around the sprocket 24 of the upper shaft 22, with one lead engaging the teeth of the sprocket 26 so that the sprockets 24 and 26 which are of the same ratio, are driven. in unison in the same direction and at the same rate of speed to turn the shafts 22 and 23 in the same direction and at the same rate of speed. The sprockets 25 and 27 are of the same ratio but are of less diameter than the sprockets 24 and 2G. r1`he shafts 22 and 23 each have loosely mounted thereon for swinging movement, a pair of longitudinally spaced arms 324-32, and 33-33. The upper pair of arms 32 mounted on the upper shaft are connected by a connectingr rod 34 at their forward ends, while the rear ends 35 are offset upwardly. The arms 33 of the lower shaft have their rear extremities connected by a connecting rod 36. Between the shaft 22 which constitutes a fulcrum for the arms 32, and the connecting rod 34, a rotary shaft 37 is journaled or mounted for turning movement and said shaft has keyed or otherwise secured thereto, a roller or drum 38 which is disposed between the arms. The shaft 37 has one of its ends extending beyond the arm and has keyed or otherwise secured thereto, a sprocket 39 which is of the same ratio as the sprocket 25. A sprocket chain 40 is trained around the sprockets 25 and 39 for driving and turning the shaft 37 and roller or drum 38. The arms 33 have journaled or mounted for turning movement in the forward ends, a shaft 41 which has keyed or otherwise secured thereto and positioned between the arms, a drum or roller 42, which drum or roller in the present instance is slightly less than twice the diameter of the drum or roller 38. The shaft 41 protrudes beyond one of the arms 33 and has keyed or otherwise secured thereto a sprocket 43 which is of a ratio with respect to the sprocket 27 to turn ap roximately one-half the rate of sneed of tie sprocket 27 by virtue of a sproc et chain 44 which is trained around the sprockets 27 and 43. This arrangement turns the drum or roller 42 at slightly less than one-half the speed of rotation of the drum or roller 38. The arms 32 and 33, their connecting rods 34 and 3G and the shafts 37 and 41, constitute a pair of frames for the rollers or drums 38 and 42, which are weighted to impinge or grip the periphery of the cloth roll R on the hatching spindle 20 at substantially diametrically opposite points to frictionally drive or turn the roll. If desired, additional or auxiliary weights 45 may be added to the weighted frames by suspending the same from the connecting rods 36 or 34. Under this arrangement the cloth roll R on the hatching spmdle 20, is held in a viselike grip between the peripheries of the two driving rollers, or drums 38 and 42, which rollers, in effect, are tensioned against relative separation.

In view of the fact that the roller or drum 38 is slightly more than one-half the diameter of the roller or drum 42 and the latter is driven at approximately half the speed of the former, the peripheral driving speed of the roller 38 slightly exceeds the peripheral driving speed of the roller 42. This exerts a constant tension on the outermost convolution of the cloth between the points of frictional driving engagement of the roller peripheries thereof and tends to positively smooth and eliminate any wrinkle or unevenncss in the cloth area.

The cloth is led or trained through a straightening frame 4G sup orted from the main frame 10 and which includes a plurality of rods 47 over and under which the cloth is alternately trained, adjustable guide plates 48 being employed in the usual manner to coact with the opposite side edges of the cloth strip. From the straightening frame the cloth is trained around a rear guide rod 49 and thence around the periphery of the roller or drum 42 and finally on to the cloth roll R. In view of the fact that the cloth is trained around the periphery of the roller or drum 42 and travels at the same eripheral speed as said roller or drum, 1t is obvious thatan accurate measurement of the yardage may he obtained by associating a counter with ,the roll 42. It is further obvious for the reason that the cloth roll driving drums travel at a constant rate of speed, that the feed will he uniform from the beginning to the end of the rolling operation, thus eliminating the tendency of the cloth to jam the guides 48 and produce Wrinkles or unevenness in the edges of the cloth convolutions on the cloth roll R. This does awa with the necessity of the constant service o an attendant so that one attendant may operate a plurality'of machines.

By ofsetting the rear end of the arms 35 as illustrated, the upper frame carrying the roller or drum 38, ma he swung to the position illustrated in otted lines in Fig. l, so that the weight of the frame will he in rear of its fulcrum with the offset portions 35 engaging the shaft 23. This supports the frame in an opened condition to allow for the insertion or removal of the hatching spindle when starting the cloth roll or removing the same from the machine.
